VALMET ND9402 Stainless Steel Intelligent Valve Controller
The VALMET ND9402 is a low-capacity intelligent valve controller from the Neles ND9000 series. Designed for accurate valve positioning and reliable industrial process automation, the ND9402 combines intelligent control technology, advanced diagnostics and robust stainless steel housing construction with a polymer composite cover.
The ND9402 series is available with three communication technologies: HART, FOUNDATION Fieldbus and PROFIBUS PA. As a result, customers can select the appropriate controller version according to the communication requirements of their distributed control system and field instrumentation network.
The ND9402 incorporates a low-capacity pneumatic spool valve intended for compatible actuators with stroke volumes below 1 dm³. Therefore, it is particularly relevant for smaller pneumatic valve actuator applications where accurate positioning and appropriate pneumatic capacity are required.
Furthermore, the ND9402 enclosure provides IP66 / NEMA 4X environmental protection. Combined with intelligent diagnostic capabilities, this design supports reliable valve automation in a wide range of industrial environments.
Available configurations include ND9402H HART models, ND9402F FOUNDATION Fieldbus models and ND9402P PROFIBUS PA models. Customers should confirm the complete model code, approval requirements and actuator compatibility before ordering.
